To. all whom it may concern:

Be it known that'I, RICHARD A. Wane HEAD, a citizen of the United States, resid-., ing at Los' Angelesj,'gin the county ,of'jLos; Angeles and. State of; California, have in-f 'vented new and useful Improvements in soundsProducing' Apparatus, of which the following is it Specification.

This invention relates to sound producing apparatus, and more particularly to means for throwing the same out of'operation at the termination of the rendition of a" song or instrumental or 'vocal selection, or such se-- quence ofsounds as may be produced in the operation of the apparatus; whereby operation of the apparatus is automatically terminated at the termination of'jsuch rendition;.and the invention has tor-its object to provide improved apparatus of the.character described, of electro-magnetic character,

which will be sup rior in point'of positive- -ness of operation, elative simplicity and in- GXPBIISIVBDESS oiconstruction and orgamza- 'tion, and sightliness in appearance, which may be applied to sound producing apparatus of standard. and conventional forms and types with but slight alteration of the same, which may be readily kept in repair, and which will be generally superior in efii- The invention consists in the provision, constructic combination, associationv and relative arrangement of parts, members and features hereinafter described and shown in the drawings, and finally pointed out in claims."

In the drawings :F igure 1 is a side elevation, partly' broken away and partly in section for clearness of illustration of sound producing apparatus, or a' so-called talking machine, organized, equipped and constructed in accordance with the invention,

Fig. 2 is a top plan view of the same, parts being likewise broken away for clearness of illustration; Fig. 3 is an enlarged detail plan View of an essential feature of the invention; and Fi 4: is a fragmentary side elevation of the eature shown in Fig. 3, and a feature of the general construction of the apparatus.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring with particularity to the drawings, the sound producing apparatus or talkmachine therein shown, as of conventional or standard form, although the invention is not limited to any specific type or form of such soundproducing apparatus,

comprises a'casing A within which is located amotorB the power of which is applied through transmission means 0 to a disk table or support D above the casing, and upon which the sound record E is disposed.

F designates the sound box within which the sounds are produced through the co-action of the point or-needle and the sound record E, G designating the tubular arm or means of direction or conduction of the sounds tothe orifice from which they exitto the auditor. The tubular arm G. is shown connected with the casing A, such casing A being of wood or other electricity insulating material. e

K deslgnates a circult maker which is disposed upon the sound record E in physical connection with the transmission means C. lV1th1n the casing A is disposed, in accordance with the invention, a battery L, or

source of electrical supply, and within said casing is likewise disposed electro-magnetic' means Mthe armature m \\-'hereof pr0jects through a suitable opening in the top of the casing in position for engagement with the periphery of the table or support D to act as a brake therefor, or means for throwing the table, the transmission means and the motor out of operation when an electrical circuit is closed through the electro-ma-gneti'c means and the circuit maker K and the point or needle The source'of electrical supply L is electrically connected with the electro-magnetic means M by a circuitwired, the electromagnet M is comi'ccte'd with the motor B by a circuitwire {5, and the bracket H is connected with ttTe" source of electrical supply L by a circuit wire 7. The sound box F is provided with a circuit wireS electrically connecting the needle or point with the tubular arm G and the connections thereof, which are found in standard practice. conducting parts of the sound box.

The

. arm G and its connections are electrically conducting, as is the bracket H, and as are the motor B and the transmission means C,

while the table I) and the sound record E are jointlynon-conducting, or at least the record E is non-conducting. \Vhcn the This circuit wire bridges the non-- wire 5 the electro-magnetic means M, the

- apparatus.

as shown, and a groove or crease 20 1s circuit wire 6,- the transmission means (3,

and the circuit maker K again to the needle f. The bracket H is insulated from the motor B by the structure of the casing A.

The circuit maker K comprises a metallic body 9, preferably circular in form," adjacent to "the periphery of which is adjustably connected an articulated guide it, which comprises a plurality of members 10, 11 and 12, which are pivotally serially connected,

as at. 13 and 14 by pins or the like, the inner-v most member 10 being piyotally connected with the body member or plate 9, as at 15. The outer member 12 overlaps the intermediate member. 11 at the point of pivotal connection 14, and the intermediate-member 11 overlaps the inner member 10 at the point of pivotal connection 13. The body or plate 9 and the articulated guide is are formed of metal or suitably conducting material. The

members 10, 11 and 12 are adapted to be adjusted with relation to the center of the body 9, wherein is formed an opening 16 whichfits the upper projecting end portion 17 of the transmission means and shaft 18, so that the plate or body 9 will be in close electrical contact with said shaft 18. The outer end portion 19 of the member 12 may be adjusted from the opening 16 and the upper end 17 of the shaft 18, over the surface of the record E, to the desired degree, with relation to the phase of the traverse of the record by the needle f at which it is desired that the needle contact with the circuit maker K to stop the rotation of the table I) and the record thereon, and terminate the operation of the sound producing The outer end 19 of the member 12 is preferably biturcatcd or forked formed in the upper surface of all of the -members-10, 11 and 12,. in continuous extension, from the forked end portion 19 to the inner end of the member 10, and thence the groove or crease 20 .is extended in a groove'or crease 20 which approaches the opening 16 spirally, and dies out into a groove 'or crease 20 circular inform and concentric with. the opening '16.

The operation, method of use andadvantages of-the improvements in sound producing apparatus, and means for throwing the same out of operation, constituting the in-- vention, will be readily understood from the foregoing description taken in connec tion with? the accompanying drawings and the following statement When the operation or the sound producing apparatus is commenced, or hefore the same is com-- menced, the meinhei Idiot guide??? is moved outwardly with relation to the .henter oi? the body 9," which is'at' the centeroi the traversed the record, in the customary man-,

ner, approxiinately"- to a pre determined point, at which the termination of the operation of the sound producing apparatus is desiredto be caused. ,The needle f is placed upon the record to initiate the production of the sequence of sounds constituting the rendition for which the record is organized,

and the motor B is put into opcration t o rotate the table 1), the record E and the circuit maker K. Whenthc needle f con-v tacts -V\71l1l1 th8 guide it, at the forked end 19, a closed electrical circu'itjis established; through'the needle, thearm G, the, bracket H, the source of electrical supply L, the

electromagnetic means M, the motor B, the transmlss'ion means and the circuit maker K, an open electrical circult having thereto iore been present in and through such parts and features'and the circuit wires joinin the same electrically. The closed electrica circuit through the electr c-magnetic means M causes the actuation of the armaturem thereof toward the periphery ofthe table D, and when brought into engagement there; with rotation of-the table andof the record E is retarded and finally checked, the motor being thus stopped through the transmission means C. Previous to final stoppage of motion of the parts-of the apparatus as last described, the needle f moves somewhat,

such movement-being accommodated by the grooves or creases 20, 20 and 20 one or all. I

of which the needle traverses until it finally comes to rest upon complete stoppage of the motor. The armature m; thus constitutes a brake for the motor B, the table D and the other partsactuated and moved by the motor, preventing, in its action upon the table 1], further-rotation of the table and the record thereon and the circuit maker' K upon the record, and therefore preventing are further relative movement of the needle f.

and the record, thereby terminating sound v production by the apparatus. Where means are not employed to throw the apparatus out of operation at the termination of a rendition thereby, the operation is continued until the motor has expended its energy,

and such operation is customarily accompanied by raucous sounds-devoid of tonal inter-relation or effect. Such expenditure of motive energy andcreation of soundsafter the rendition -hasbeen completed, are prevented and obviated by the'use of the improved means described for throwing out of operation the seu'nd producing apparatus and the actuating means therefor; and it maybe noted that the guide 7;, because of its adjustability, may be so disposedwith relation to the center of the record E as to cause termination of .operation of the apparatus at any pre-determined phase there of, or substantially at any pre-determined point 111 the rendition of the selection for.

which the record is organized.

In equipping or providing sound producing apparatus of standard or conventional types with the impimvements constituting the invention, very slight alterations are necessary, comprising in the main the installation of the electro-magnetic means M,

the source of electrical supply L, the circuit maker K, and the several circuit wires for electrically connecting the parts.

It will be understood that thebrake ordi-- narily provided for stopping the operation of the apparatus, and manually controlled,

may be retained for use in connection with the improvements constituting the invention, so that the apparatus may be maintained inoperative during the changing of records, and previous to commencing the sound production. Such retention of the brake customarily employed is optional, as will be manifest. The apparatus provided with the improvements is neat in appearments to varying conditions of use, Without departing from the spirit of the invention and the terms of the following claims.

Having. thus described my invention I claim and desire to secure by Letters Pate ent 1. In apparatus of 'the character described, a movable sound record support,

the sound record thereon, a needle co-act-ing with the sound record in the production of sound, an adjustable support for'the needle, 3
